      This sample demonstrates the RealtimeDragSelectingTool, which replaces the standard <a>DragSelectingTool</a>. Press
      in the background, wait briefly, and then drag to start selecting Nodes or Links that intersect with the box. You can
      press or release Control (Command on Mac) or Shift while dragging to see how the selection changes.
    </p>
    <p>
      Load it in your own app by including <a href="RealtimeDragSelectingTool.ts">RealtimeDragSelectingTool.ts</a>. Initialize
      your Diagram by setting <a>ToolManager.dragSelectingTool</a> to a new instance of this tool. For example:
    </p>
    <pre>
myDiagram.toolManager.dragSelectingTool = new RealtimeDragSelectingTool();
    </pre>
    or
    <pre>
$(go.Diagram, { . . .,
                "toolManager.dragSelectingTool": $(RealtimeDragSelectingTool, { isPartialInclusion: true }),
                . . . })
    </pre>
